Servicing
8.4 Removing coupling part 1 (1) or 3 (3)
50 Edition 09/2022 M3602-01en
DANGER
Danger as a result of improper handling of fixtures and pumps
Failure to handle fixtures and pumps properly can result in injuries and cause the coupling
to burst. There is a risk of fatal injury from flying fragments. Bursting of the coupling can
lead to an explosion in potentially explosive atmospheres.
• Please observe the manufacturer's information on handling the following tools:
ð
Pulling fixtures
ð Pumps
WARNING
Risk of injury as a result of coupling components or the pulling fixture working
loose
Coupling components or pulling fixtures can work loose and fall when dismantling work is
in progress.
• Use suitable hoisting gear to hold the coupling part 1 (1) or 3 (3) and the pulling fixture
in position.
• Attach an axial locking element if the pressurised oil interference fit is tapered.
NOTICE
Risk of injury and danger to the environment from escaping oil.
• Catch any oil which escapes.
• Dispose of the oil according to the valid regulations.
Tools required
• One oil pump with pressure gauge (at least 2500 bar) per oil channel.
Or:
One motor-driven oil pump. One connection that can be closed independently is required
for each oil channel.
Refer to the dimension drawing for the number of oil channels.
• With a stepped bore:
A motor-driven oil pump at the oil channel located at the point of transition from the smal-
ler to the larger bore. A large quantity of oil per unit of time is needed here.
• Suitable connections and pipes.
• Suitable pulling fixture.
Or:
Retaining plate with retaining screws or threaded spindles with nuts. Material of the
screws and spindles must have at least strength class 10.9; material of the nuts depend-
ing on the material of the screws or spindles.
• Hydraulic cylinder with oil pump. Note displacement and pressure of the hydraulic cylin-
der. Refer to the dimension drawing for the required axial force.
Procedure
1. Move the coupled machines apart.
